TypeError: e.reduce is not a function

I am unable to use V Ray for Rhino because the V-Ray Log Window Launches with the error “TypeError: e.reduce is not a function”.

What does this mean and how do I fix it?

Hello @carl_harris ,
Thank you for posting and I have noticed that you have also opened a ticket to our system with this inquiry.

Please let’s continue communication in ticket for now, for which please share as requested in the ticket:

  • Rhino version. (Help>About Rhinoceros)
  • V-Ray version. (V-Ray>Help>About V-Ray) If the version you are using is not the latest 6.00.03 version please try to update V-Ray.
  • Does it happen in every scene? Please test any simple scene.
  • Can you recall if the error message occurs when you try to render, edit materials or add materials from Cosmos Browser, etc.?

Thank you in advance.
